Question

Which function is the inverse of f(x) = 2x + 323ƒ^²^²(x) = -1/1/2ƒ^²(x) = 1/2 x - 1²/20Of¹(x) = -2x + 3Of(x)=2x+3

Answer 1

Given: A function F(x)=2x+3 is given.

Find: inverse of a function.

Explanation:

`\begin{gathered} f(x)=2x+3 \\ y=2x+3 \\ x=2y+3 \\ y=(x-3)/(2) \\ f^(-1)(x)=(x)/(2)-(3)/(2) \end{gathered}`

Final answer: the required inverse of f(x) is

`(x)/(2)-(3)/(2)`
